Quantum corrections to dielectric response in the weakly-degenerate regime.
Insights into Dirac-cone systems with linear dispersion.
Abstract
Analytical results for the dielectric function in RPA are derived for three-, two-, and one-dimensional semiconductors in the weakly-degenerate limit. Based on this limit, quantum corrections are derived. Further attention is devoted to systems with linear carrier dispersion and the resulting Dirac-cone physics.
